SPECIFICATION forming part of Letters Patent No. 554,197, dated February 4, 1896. Application filed November 6, 1895. smart. 568,095. (no model.)

To aZZ whom it may concern.-

7 Be it known that I, ALBERT L. PITNEY, a citizen of the United States, residing at VVashington, in the District of Columbia, have invented certain new and useful Improvements in Gas Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in heating-stoves adapted for the use of gas; and the object is to provide a stove which will be economical in the use of gas without reducing the heating capacity.

The invention is fully described in the ac companying drawings, forming a part of this specification, and wherein- Figure 1 is a vertical sect-ion of the com-,

plete stove. Fig. 2 is a sectional view of a modified form of the combined spreader and radiator.

A designates the base, which is made of such dimensions as to maintain the stove in an upright position. In the present instance (and preferably) sheet metal is used, although any suitable material would answer the purpose.

The base or stand A is preferably circular in form and of any ornamental design, and has formed at the top thereof an annular ring 1, over which the lower end of the cylindrical column 2 fits and being connected thereto by rivets 4.

In the shell of the base A are formed a number of holes 3, through which the air passes to mix with the gas before it is burned, also to prevent the base A from becoming too hot and burning what it may be resting upon. The cylindrical column 2 is also provided with openings 5 to insure sufficient air for V mixing with the gas, the same being located part of the globe adjacent to the bottom part of the flange 10 are a number of openings 12, through which the hot air escapes. The cap 11 is also provided with openings to allow of the passage of hot air from the inside of the globe.

The globe B is made in two parts 13 and 14. divided at the horizontal central part, the upper section, 13, slipping over the lower section, 14, the sections being held in alignment and together by means of a flange 15 formed on the upper section, 13.

The reason for making the globe in sections is that the upper part may be lifted off the lower part to put in or take out the burner or spreader, as desired.

In the column 2 is arranged a gas-pipe 18, suitably formed at its outer end to have connection with hose, &c., leading from the sup ply-pipes, and having its inner end, 19, bent at right angles and directed upward, as shown. In the end of 19 is placed an ordinary lava gas-tip 20. On the pipe 19 is fitted shell of burner 21, having its lower part, 22, contracted and formed with a neck 23, which fits over the end of pipe 19 and permits tip 20 to have a clear opening into burner 21. The part 22 is provided with openings 24 to admit the'air. into the burner to mix with the gas before it is burned. The burner-shell is made of sheet metal and slightlyfiaring at the top to give more surface for the burning gas on its upper and outer surface, which is formed by using wil'e netting 6. Over this wire-netting, to hold it in place, is fitted a metal ring 25, having prongs or projections 26 extending upward and intended, in this case, to support the spreader 27 The spreader 27 is a circular piece of solid sheet metal reaching almost to the sides of the globe and intended to spread the flame so that it will impinge upon the inner sides of the globe and heat them, thereby causing outer radiation, this being the object of the peculiar form and-size of the spreader and its close proximity to the burner.

In the lower part of the globe are shown a number of circular openings 29 intended to admit air to mingle with the flame from the burner and also to allow outer radiation from the under side of the spreader. m

In Fig. 2 is shown a modification in the form of the spreader, the edge being turned upward for the purpose of directing the flame against the sides of the globe.

The operation or use of my improved heater is apparent from the construction shown in the drawings, when taken in connection with the description thereof, whenever the respective functions of the parts are specified, but the combined operation may be rehearsed as follows: The gas having been turned on and allowed to mix with the air in the body of the burner, and having by its natural buoyancy and the current formed by the pressure in the pipes been forced upward through the wiregauze in the top of the burner to the open space between the top of the burnerand the-bottom of thespr'eader, it is ignited by means of a light passed closely to or into the openings in the bottom of the globe, when instantly the flame from the burning gas and air spreads all over the bottom of the spreader and upward between the edges of the spreader and the sides of the globe, reaching to and beyond thehorizontal central dividing-line of the upper and lower halves of the globe. In a very few seconds the spreader becomes red-hot, the sides of the globe heated in like manner, particu larly in the lower part. The radiation from the upper part of the spreader passes out of the globe through the upper openings, and the radiation from the lower part of the spreader passes downward through the openings in the lower part of the globe. The outer sides of the globe radiate in all directions. No part of the heat contained in the gas is wasted.

Vith the arrangement of the parts of the device as' shown it is possible to get a very large amount of heat from a very small amount of gas.

WVhile the form of burner herein described has been found in practice to be very efficient it will however be apparent that any form of burner may be employed without departing from the spirit or intent of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a gas-stove, a base or support, a chamber mounted thereon, a burner supported within said support and a deflector above said burner having its edge contiguous to the walls of said chamber, substantially as described and the walls of said chamber being upwardly inclined from the plane of said deflector whereby the products of combustion are maintained in contact with the walls of said chamber for a considerable portion of its extent as set forth.

2. In a gas-stove, a base or support, a heating-chamber connected thereto and having the walls of said base extending into the chamber beyond the point of connection, and a gauze supported upon the walls of said base within the chamber and means for feeding gas and air to the space below said gauze, substantially as set forth.

3. In a gas-stove, a cylindrical base or support, a heating-chamber made in globe form having a rim or flange formed therewith by which to connect it with the base, with the walls of the base extending into the chamber, a gauze to cover the end of the base, a burner supported in the base, and a deflector consistin g of a plate or disk arranged within the globe with the edges extending nearly to the walls of the globe substantially as described, whereby the products are caused by the plate or disk to be deflected outward and follow the curved outlines of the globe as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT L. PITNEY.
